Abstract (en)

[origin: EP1560231A2] Provided is a magnetic resistance device in which a pinning layer, a pinned layer, an anti-ferromagnetic layer, and a free layer are sequentially formed, and the free layer is formed of an intermetallic compound. The magnetic resistance device provides a high MR ratio, thereby increasing a sensitivity margin.
